Features
- Hytork XL comes with a unitque SAFEKEY system (patented) and uses a flexible stainless steel key in an internal machined keyway. SAFEKEY prevents external contamination and eliminates stress concentrations caused by point loading.
- Actuator internals are protected for corrosion with CEREMIGARD a ceramic-like finish of Di-Aluminium Tri-oxide (Al2O3).
- A powder-coated surface treatment as standard on end caps and housing provides extra protection against aggressive environments.
- All moving parts are protected by permanently lubricated and long-lasting DURASTRIP bearings to reduce friction and increases cycle life.
- Plated with cobalt zinc, the steel pinion is protected from corrosion and features a unique stop design.
- NAMUR mounting (VDE/VDI 3845) allows standardization of mounting hardware for a wide range of accessories.
- Hytork XL actuator pinion drives are manufactured to ISO 5211 with a star drive to provide extra flexibility and simplicity for direct mounting to a valve.
- Large internal air passages maximizes valve operating speeds and adds reliability by reducing potential blockage.
- The visual position indicator is designed for indication at a glance and can easily be converted from across-line to in-line indication.
- The bi-directional travel stops allow easy setting of the valve stroke which prevents premature valve failures.
- Extra large rack and pinion tooth design promotes full tooth engagement. Assists gear tooth life by reducing stress and having precise gear tooth mesh.
- XL Springs are designed and manufactured never to break. The nested design provides a balanced concentric force on the pistons.
